ToaZZ 'whom t may' concern:

Be it known that I, EDMUND H. LuNxEN, a citizen of the United States, residing 'at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Shade-Screens, of which the following isa specification.

My chief object is to impart. to a window screen, of such material as the ordinary wire netting, the attributes of a shade or awning so that in one article, occupying the space oan ordinary window screen and capable of being commercially producedand handled as readily as the ordinary product, there will be combined all `of the advantages of a window screen in the matter of admission of light and air and exclusion of dirt and insects, and all of the advantages of a shade or awning. without additional expense such as incurred in the installation andupkeep Vof the usual awnings. To accomplish this I propose to'convert such material as the ordinary woven wire sheeting into a zigzag form and mount it in a frame or sash so that alternating divisions or zones will slope or stand obliquely and overlap to intercept the direct rays of the sun, and these portions of the screen I propose to render opaque. The intervening divisions or zones of the screen I propose toleave in their ordinary state for the admission of air and light, preferably having them also extend obliquely S'o that a view may be had through them from the inside.

In the accompanying drawings I have illustrated different forms in which my invention may be carried out.

Figure l is an elevation of part of a window screen as it would be seen. from the exterior of a house; Fig. 2 is a vertical sec'- tion of the same; Fig. 3 shows a portion of one of the side pieces of the frame or sash in the flat or blank form; Fig. 4 isaperspective view of the same bent to final form; Fig. 5 is a view similar to Fig. -1 but illustrating a different mode of carrying out. the invention; Fig. 6 is a vertical section of the same on a larger scale; Fig. 7 is a section of part ofthe screen similarly shown in Fig. 6, the -screen wire being exaggerated in size and contour to better illustrate the treatment thereof to produce the opaque zone; Fi Y. 8 shows in elevation a portion illy woven wire netting used in the construction illustrated in Figs. 5, 6 and 7 Referring first to Figs. 1 and 2, the refting of the ordinary square-mesh type such as commonly used in window screens. For the purposes of my invention a sheet ofthis netting is bent to zigzag form, as clearly 4`illustrated in Fig. 2, so that there may be presented outwardly to the suns rays a series of overlapping oblique divisions or zones a separated by ppositely inclined divisions or zones b, the latter preferably not extending on as sharp an angle as the zones a.

-In the construction illustrated in Figs. 1

and 2 the divisions or zones a are treated to render them opaque by the application on the exterior of sheets of suitable material erence letter A designates woven wire netsuch as canvas ortar paper, oil cloth or the: like, designated by the letter c. These sheets or strips of material cover the entire area'of the'dlvislons or zones a and may be attached 4thereto in any suitable manner, vas for example,by stitching them to the woven wire or, applying metal clips. preferably applied on the outer sides of the divisions or zones a of the screen, though they would be effective applied't the innersides thereof, or such sheets might be.ap.

These sheets are plied onboth sides. In any case, it will be' obvious that the alternating divisions or zones so treated will be rendered opa ue and by reason of their inclination and re ative arrangement will effectively intercept the direct rays of the sun and exclude sun-4 light from the interior of the room in the window of which this screen so made up is mounted. At the same time it will be clear that the intervening divisions or zones b will .i

admit light and air freely and afford adequate ventilation, besides permitting a fairly extensive view to be had through -them looking from the interior.

A zigzag sheet of wire netting such as above described. may be mounted in various forms of sashes or frames. have here shown, however, what I believe to be a vnovel construction and on'e possessing superior advantages. such as galvanized iron or sheet steel and `comprises side pieces B and top and bot-- tom pieces C. The side ypieces are especially constructed to receive and holdl the zigzag netting. Each has the same construction and the description of one will suiiice for both. A single sheet 'of metal is employed stamped out with the contour illustrated in Fig. 3, punched for fastenings, such as bolts or "rivets, and bent on the dotted lines there It is composed of sheet metal V shown. This sheet comprises a central portion ci which forms the outer side ot the complete bar; tivo lateral portions d and Z2 which extend beyond the central portion d at both ends and are punched with holes Z3 in these extensions and also with holes d in their body portions; and a series of saw teeth d5 CZ along the outer sides of the lateral portion d d'2 respectively, t-he teeth of one series being staggered W'ithrelation to the teeth of the other so that when the blank is bent to iinal shape these tvvoseries ot teeth vvill interlock as illustrated in Fig. 4.

llt will be understood that the blank is iirst bent along the lines e separating the central portion al from the lateral portion d," d2, which bending may loe done in the same process with the stamping out ot the blanlr or sheet. The lateral portions UZ d2 are thus brought at right angles to the central portion d. Thenthe savv teeth are bent at right angles to the lateral,l pjortion d d2 along lines e, Fig. 3, and the eavv teeth become interlocked as illustratedA in Fig. t. It will be obvious that the confronting edges of the savv teeth will form between them a zigzag channel and it is in the channels ot' the tvvo side members ofthe 'frame or sash.

that the 'zigzag sheet of netting is arranged and held. This may readily be accomplished by springing open the formed up side'pieces, introducing the side portionot the zigzag sheet of netting between the teeth and then permitting the latter to close upon the same. Fig. 2 represents the netting so secured and it will be obvious that by inserting it in to the hollow side pieces to the extent illustrated in dotted lines in Fig. l it will be very secure against disconnection from the frame or sash.

The top and bottom members of the sash are alike, each comprising a piece of sheet metal C bent to rectangular form as shown in Fig. 2 with inner portions hl overlapping. Between these overlapping portions the upper or lower edge or marginal portion of the sheet, as the case may be, is introduced, as illustrated in Fig. 2 and clamped. This .membcr of the sash or frame is fitted between the extensions of the two side members d @Z2 and secured thereto by suitable rivets y or-the like. Similar tastenings g' may be employed to clamp the side members upon the Wire netting.

It will be obvious that lthe above described construction of frame or sash possesses advantages in the matter of facility ot manui handle, and that it will not present an unsightly appearance.

liteterring novv to the form of embodiment inname ot my invention illustrated in Figs. 5 to 8, here, instead ot using the ordinary vvire netting throughout and treating alternating divisions or zones by applying sheets ot' opaque material thereto, as in the construction already described, l render these divisions or zones opaque by more closely Weaving the same and lilling the interstices. l" will be understood that in the ordinary netting, Wire for the vveft is `carried baclr and forth so as toV make a square mesh with the warp Wires as illustrated in Fig. 8 in the portions ot a sheet of netting there designated z. A finer mesh may be had for the purposes oit my invention by running the weft Wire much closer, a'. c. bringing the strands in closer proximity, as illustrated in the sections of said sheet of vvirey netting designated z' in Fig. 8,producing a small oblong mesh. The purpose is not so much to approach opacity by the mere matter of closing the lvveft strands together, but to so construct the interstices that they vvill readily retain a tiller such as' solder, paint, or other plastic material. This is illustrated in an exaggerated Wa in Fig. 7, Where the reference letter j in icates the vvarp vvireand 7e the Wett vvire and n the iiller. This filler may be applied in any appropriate manner as by painting it on with a brush trom tively render the divisions or zones ofthe screen opaque and it possesses advantages' in the matter of ease of application of the material and in the matter of renevval, since fresh coats of paint or other material canmercial advantages. For instance, a manufacturer oii Wire netting canlturn out the product with the alternating tine mesh divisions or zones,'and this product can be handled in rolls as is ordinary vvindovv screeny netting and supplied as a staple ar ticle. At the screen factory this article can lbe treated to produce the zigzag sheet,-as by the use of shaping dies or rolls,-and also to render the alternating tine mesh zones opaque. T have already commented upon themanufacturing and commercial advantages oi' the particular construction ot sash or trame here shown, and it will be obvious that assembling of the same With the prepared zigzag sheets can be expeditiously and economically carried oneither at the same place Where the sheets are produced, or at distributing points, whence the sheets and trame or sash pieces are shipped in knock-down state.

lllhile the netting of alternating coarse and i'ine mesh. is desirable as retaining the characteristic oi" transparency to much the 95 one side or both. Ubviously this will etiecsame extent as an ordinary window screen, 'it will be clear that the entire sheet might be of fine mesh, alternating zones being treated for opacity. Such construction might be preferable where exclusion of dirt was specially called for, as, e. g., on railway trains. As will be apparent, the invention is capable of being practised in numerous ways V and with varying modifications, all of which I do not attempt to oint out :or predict, but, having particular y pointed out certain -speciiic forms of embodiment, Ilcontent myself with reciting essential elements in appended claims,`withoutlintended limitation to the exact forms of embodiment here shown and described but rather. with the idea ofy broadly expressing the essential characteristics of in invention, separate and distinct claims eing employed to re- ,i cite-speciiic structures. g Y
